Hydraulic tappet for direct interposition between a cam 7 and a valve stem 8 of an overhead cam-shaft I.C. engine comprises a tappet body 1 slidable in a guide 4 and housing an annular fluid reservoir 14 which surrounds an automatic slack take-up device formed by a plunger 2 in a cylinder 30 the pressure chamber 3 of which is connected via a non-return valve 19 to the reservoir 14, which in turn is supplied with oil from the engine lubrication system. The cam bears on a wear resistant plate 6 at the top of the tappet. The valve stem 8 abuts the plunger 2. While the tappet engages the base circle 20 of the cam, oil from a line 10 can enter the reservoir 14 via a gallery 12 and a port 13 in the tappet body 1. A port 15 in the cylinder 30 opens to an annular groove 16 round the plunger 2 to feed the non-return valve 19, and faces away from the port 13 to prevent air from entering the pressure chamber 3. When the tappet is deflected by the cam rise, the port 13 is opened to the atmosphere, via a chamfer 23, to prevent "pumping" of the tappet, and a port 26 is uncovered to direct oil on to the cam and the plate 6. The tappet body and cylinder are formed integrally by deep drawing. An alternative tappet body (Fig. 2, not shown) engages the cam with its upper end, the outer wall and the cylinder depending from said upper end. A closure plate (29) seals the lower end of the reservoir.

Title: Improvements in or relating to a quick disconnect pipe coupling
IPC: F16L37/107
Filed: 1957-06-25
Abstract: 844,258. Pipe couplings. WEATHERHEAD CO. June 25, 1957, No. 20064/57. Class 99(1). In a pipe coupling comprising in each coupling member A, B, a rotary valve 10 actuated by rotatable rings C, D, a locking member 108 which prevents rotation of the ring C and hence locks the valve 10 in the member A in the closed position when the coupling is disconnected is rendered inoperative when the coupling members are connected. The rings C, D are mounted on stationary body members 14, 128, and carry racks 84 which mesh with pinions 36 on the valve spindles 10, the coupling members being connected by a bayonet type connection comprising undercut lugs 86, Fig. 2, on the ring C which co-operate with projections 133, Fig. 3, on the body member 128. The ring D carries projections 132 which engage between the lugs 86 on the ring C to connect the two rings for rotation together. The ring C is connected to a rotatable collar 98 and the locking pin 108 is mounted in the body member 14 and has a projection 110 which engages a recess 114 in the ring C to prevent rotation of the ring relative to the stationary member 14 when the coupling is disconnected. A spring- loaded ball 150 also engages a recess 152 in the ring D to hold the ring D releasably locked in the valve-closed position when the coupling is disconnected. On connection of the coupling the spigot end 16 of member 14 is inserted axially into the socket 136 of member 128 which member simultaneously forces locking pin 108 back to release ring C. The collar 98 is then rotated to turn sleeve C which, through engagement of the lugs 86 with projections 132, also turns ring D so that the valves 10 are rotated to the open position simultaneously. The rotation of ring D also causes the lugs 86 to engage the projections 133 in bayonet fastening fashion and lock the coupling parts A, B, together, the collar 98 being locked in its coupling completed position by a spring-loaded ball 120 carried by the body part 14 engaging an aperture 126 in the collar 98. The valves 10 are coupled to their spindles 20 by a tongue 26 engaging a groove 24 which lies parallel to the flow axis when the valves are closed, permitting a spring- loaded sealing sleeve 42 to move the valve laterally to seat tightly against a sealing ring 40 of "Teflon" (Registered Trade Mark) when the coupling is disconnected. The threaded pipe connector 58 is rotatably connected to the body member 14 by a split retainer ring 74 which engages in recesses 68, 70, of the connector 58 and body 14 and is secured by a retaining ring 78 and washer 80 ; the corresponding pipe connector 148 of the member B is secured by a screw-threaded connection 146. A dowel pin 116 in the body member 14 engages a corresponding recess 134 in the body member 128 to ensure correct location of the parts during coupling.

Abstract: 1,103,483. Transistor sawtooth circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. 14 May, 1965 [14 May, 1964], No. 20127/64. Heading H3T. In an integrator or sawtooth waveform generator in which a capacitor is linearly charged via a circuit 2 and subsequently discharged via a transistor 3, the voltage at the onset of each charging period is clamped by feeding back the voltage across the capacitor via a D.C. amplifier to a tapping in the base bias resistor of the transistor 3. As described, transistor 3 is cut off by a negative-going pulse at 17 so that capacitor 1 charges via resistor 2, the charge being linearized by bootstrap feedback via a D.C. amplifier 22, 24 and capacitor 27. The charging current also flows into the base of transistor 8 turning on this transistor which maintains transistor 3 non-conductive after the offset of the pulse at 17. Capacitor 1 continues to charge until transistor 22 bottoms, when the charging current is diverted from transistor 8 so that this transistor becomes cut off, turning on transistor 3 and rapidly discharging capacitor 1. Diodes 28 and 29 now become conductive, recharging capacitor 27 and clamping transistor 3 so as to prevent saturation and stabilize the starting potential across capacitor 1. The cathode of diode 29 may alternatively be connected to the emitter of transistor 22 or the collector of transistor 3. The charge may alternatively be limited by a catching diode. Diodes 15, 16 provide temperature compensation. Silicon diodes 19, 21 protect transistor 3 against excessive negative voltages whilst diode 20 provides D.C. restoration.

A wire-wound fixed or variable resistor has a protective and insulating coating or covering comprising a silicone and a mineral filler such as silica. It is stated that silicones in general are classified as fluids, varnishes and resins, and rubbers and that any of these classes of silicones can be used in the present invention provided they are in a form capable of being treated with a thinner and mixed with a powdered mineral filler to produce a viscous mix. In the embodiments described the silicone used is a silicone resin or varnish. The covering is heat-cured at a temperature (a) below the firing temperature of vitreous enamel; and (b) sufficiently low to avoid a chemical or physical change, e.g. oxidation, within the metal of the resistance wire which is wound as bare wire on a ceramic or other insulating former which may be a tube for a fixed resistor and a solid ring for a variable resistor. An example coating composition is a suspension mixture formed by mixing with the silicone a thinner such as toluene or naphtha and then adding a powdered mineral filler such as silica. The invention is described with reference to a fixed resistor, Figs. 1 to 4 (not shown) and to a rotary-type sliding contact variable resistor, Figs. 5 to 7 (not shown).
